Police have impounded a man's car after he was caught speeding past an unmarked police car at more than 70km/h over the limit in Melbourne's south-east.

Frankston highway patrol officers stopped the 33-year-old Mornington man after observing him doing a burnout, then speeding east on Cranbourne Road, Langwarrin, at 151km/h in an 80km/h zone about 10.15pm.

Police say the driver will be charged on summons with several traffic offences, including dangerous driving.
